Dear Friends, I have problem with OWA in Exchange 2003. I have one Windows 2003 domain controller and exchange 2003 is running on the same machine. MY Exchange 2003 including OWA over HTTP is running fine. I wanted to enable OWA over HTTPS. I have installed certificated services and configured my DC to be an enterprise root CA. Now when I got IIS admin I'm not bale to generate certificate request from my Virtual site. Any one had similar issue?? Regards, Rajnish Malik
